Kep1er just released I do! Do you? and I think it's a great song with fun vocals and a groovy base. Stayc's Poppy is also a great Japanese release.
My question is why Japanese releases are so ignored by the international Kpop community. It's not like the language difference matters that much. And while Japanese releases are usually brighter, it's not like Korean releases are never bright either.
Are there any Japanese releases you feel has been overlooked because it's Japanese?
